Specification of Letters Patent.

Patented heh. 20", 1917.

Application filed February 12, 1915. Serial No. 7,792.

1 b all whom it may concern:

Be it known that I, WALLACE W. CASE, a citizen of the United States,residing at Peru, in the county of Miami and State of Indiana, haveinvented new and useful Improvements in \Vheels, of which the followingis a specification.

This invention relates to wheels and more particularly to spring wheelsfor vehicles. The principal object of the invention is to improve uponthe type of wheel disclosed in my cr')- )encling application Serial No.822,441, filed March 1, 1914. In this application one of the objects wasto provide a wheel constructed of a plurality of arcuate folly and rimsections so connected that they had relative movement one with the otherfor the purpose of insuring proper flexibility and resiliency to take uproad shocks. It is now an object of this invention, as before stated, toimprove upon the structure shown in the above mentioned application byproducing a more eli'ective joint between the sections which not onlyprevents lateral movement between the sections but which facilitatestheir relative radial movements and obviates noise.

Further objects ofthe invention will appear as the following specificdescription isread in connection with the accompanying drawing, whichforms a part of this application, and in which Figure 1 is an elevationof a portion of the wheel showing an improved type of felly.

Fig. 2 is a detail perspective view of one of the felly sections withthe rim section removed.

Fig. 3 is a detail sectional view on the line 33 of Fig. 1.

Referring more particularly to the drawing, 1, 2 and 3 indicategenerally the hub, spokes and felly respectively, and 4 indicates therim in which the tire 5 is seated. The hub 1 is made in any preferredmanner and is arranged so as to clamp the spokes 2 thereto, these spokesconsisting of substantially S-shaped resilient strips of metal whichconnect with the folly 3 by means of the bolts 6.

The felly 3 is constructed, as shown, of a plurality of arcuatesections, each section having at opposite terminals inwardly andradially extending lugs 7 and 8, the former projected oircumferentiallyand has its face formed on the arc of a circle, as shown at 9, while thelatter lug 8 is re cessed or concaved so as to receive the projectedface of a lug 7. The lug 8 is provided with a longitudinal slot 10 whichreceives a set screw 11 carried by the lug 7 of the adjoining section.This slot is extended throughout the length of the lug 7 So as to givefree movement of the adjoining section, but it will be seen that as theset screw enters the slot and travels therein in all relative radialmovements of the sections any relative lateral movement of the sectionsis prevented.

The rim is also constructed of a plurality of sections, each of whichhas a length coextensive with the felly section to which it is attachedby means of the bolts 6 but is slightly loeveled'at its ends, asindicated at 12, so as to permit radial movement of the sections withoutseparating the lugs 7 and 8 of adjoining sections and permitting them ofwhich is to rock readily upon each other in the mannor of a hinge. Eachrim section is, of

course, suitably formed to provide a circumferential groove when thesections are joined together for the reception of the tire 5.

l/Vhat is claimed is A wheel comprising a felly constructed of aplurality of sections, radially extend ing lugs on opposite ends of saidsections and circumferentially projected, certain of said lugs having aconcaved confronting face provided with a centrally located elongatedslot, the other of said lugs having their confronting faces formed onthe arc of a circle and adapted to enter and contact with the concavedfaces of the former mentioned lugs, a screw carried by the lattermentioned lugs and extending through the slot of the other of said lugsand adapted to travel therein in all relative radial movements of thesections, and further preventing any relative lateral movements of thesections, a hub, and spring spokes connecting the hub and fellysections.

In testimony whereof I affix my signature in presence of two witnesses.
